(CH. Eli-39) '7 Claims.

This invention relates to cooking stoves and has for one of its objects, the provision of a stove construction, by means of which, as applied to a gasrange, more efiicient operation is eifected in the burning of gas and greater ease is provided for maintaining the parts in proper operating and sanitary condition.

A further object is-the provision of a stove construction wherein the burner operating valves may be centrally located at a point, adjacent the midportion of the burner box, and wherein gas for each burner is automatically ignited, whenever the valve therefor is opened. In this connection, my invention contemplates a novel arrangement of drip pan and burner construction, which will present a neat appearance, be easy to clean, and which will economize space vertically, thus leaving a relatively large utensil compartment in the lower portion of the burner box.

The preferred means for carrying out my invention is illustrated in the drawings, wherein .Fig. l is a top plan view of a gas range embodying my invention; Fig. 2 is a horizontal section taken through the stove shown in Fig. 1; Figs. 3 and 4 are sections taken on the correspondingly numbered lines in Figs. 2 and 3 respectively; Fig. 5 is a longitudinal vertical section through one of the drip pans; Fig. 6 is a top plan view partially in section of a hood for the gas manifold; Fig. 7 is a top plan view of a burner; Fig. 8 is a section taken on the lines 8-8 in Fig. '7, and showing the relationship between the burner and the manifold hood, and Fig. 9 is a, front view of part of the stove front and illustrates the burner control handle arrangement.

My invention is applicable to that type of stove or range, which has an oven box 10, and a burner box 11 disposed in side by side relationship upon a common frame. Burners are illustrated at 12, as being disposed in the usual positions in the burner box, and beneath grates 13. The gas supply manifold is illustrated at 14 as extending through the midportion of the burner box from the back to the forward part of the stove, and between the burners. Suitable branches controlled by valves 15 then extend laterally from the manifold, and communicate with the fuel conduits 16, which lead to the respective burners.

The drip pans, which form part of my invention are curved members 20, which are supported on a shelf 21 that extends around the marginal edges of the stove frame. These pans are removable and are provided with curved openings 22', which provide adequate clearance for the elbows of the fuel conduits 16. The upper portions of Serial No. 569,667

the openings terminate in slots 17, as shown in Fig. 5, that provide shoulders in which the outer lower edges 23 of the burners are adapted to be supported. The shape of the pans and the position of the slots are so determined that the burners may be snapped into position, and securely held against tilting when the mouth of the conduit 16 is positioned over the nipple 23, which is connected with each valve. The pans therefore, serve not only as collectors for any material that may be spilled on the stov but also as a closure for the upper portion of the stove, and as a means for conducting fresh air into the burners.

The manifold and the associated valves are covered by a hood 25, which extends from the front to the back of the stove and is supported upon the shelf 21 and beneath the grate. The hood is illustrated as a U-shaped member, which has a close-fitting engagement at 26 with the drip pans, and therefore cooperates therewith to provide a conduit for air that is used to support combustion. To this end, air inlet openings 27 may be positioned in the back of the stove, so that the entire front 28 may be closed and thereby present a relatively smooth and pleasing 0 appearance. ,v

The hood also cooperates with a pilot light 30 to cause ignition of gas automatically whenever the valve to any of the burners is turned on. This 'may be accomplished by locating the pilot at the center of the burner box, and within a pocket 31 in the upper part of the hood. Suitable conduits 32 then extend diagonally from the pocket to the respective burners, while each burner is pro- 'vided with an opening 33 in the side wall thereof,

and approximately in alignment with the adjacent passageway 32. Thus, whenever any particular valve is turned, gas from the associated burner flows through one of the passageways 32 and is ignited by the pilot. This flashes back, and ignites the burner. In Fig. 8, there is shown a clearance between the end of'the passage 32 and the port 33, for enabling the ignited gas to light that which flows from the top of theburner. The manifold and hood arrangement embodying my invention is well adapted for a central compact superimposed arrangement of the valve operating handles 35, for in each case, the handle may be directly mounted on an end of the valve rod 36, which is attached at the inner end to a 05 standard form of gas valve. Furthermore, the center manifold permits the use of a uniform length of fuel conduit to the respective burners. The coaction between the manifold hood and the drip pans to direct the air, insures a constant the burner box.

supply of :fresh air, and a moving current of cool air around the valves. This prevents them from sticking, for the grease on the valve is not dried out by heat. Other advantages are that the conduit cap or hood is removable for adjusting the valves without requiring the removal of the burners or tray. Furthermore, the pilot is adjustable by means of a set screw (not shown) adjacent the outlet and does not necessitate the use of a relatively small opening, as is the case with the flash-type of lighters. The arrangement of the valve handles in the front center portion of the burner box keeps them in a cool zone, where they may be easily and readily operated.

The gas supply to the oven burner 40 may be taken through a branch 41 that extends downwardly from the manifold, and is controlled by a valve 42 through an operating handle 43, which is positioned adjacent the forward midportion of Such branch may be readily connected to a thermostat 45 and thence to the oven burner, which is also supplied with fresh air from that portion of the burner box beneath the'pan 20.

I claim:

1. In a stove, the combination with a frame, of a plurality of burners therein, curved drip pans removably supported on the frame, a removable hood coacting with the pans to provide a bottom closure for the burners and to conduct air for supporting combustion of gas in the burners.

2. A stove comprising in combination, a frame, a plurality of burners therein, a gas supply pipe extending from the rear to the front of the stove and between the burners, a hood for said pipe, and curved drip pans supported on the frame and coacting with the hood to provide a conduit for conveying to the burners substantially all of the air for supporting combustion.

3. In a stove, the combination with a burner box frame having air supply openings at the rear thereof, a gas supply conduit extending from the back to the front of the stove, a plurality of burners, a valve for each burner, branch connecmasses tions leading from the supply conduit to the respective burners, a hood for said conduit and valves, and drip pans supported on the frame and engaging the hood and providing a support for the burners, said pans coacting with the hood to conduct air to the burners through said openings.

4.
